We theoretically propose and experimentally demonstrate an active quasi-static magnetic cloak enabled BROMELAIN by a single magnetic dipole.The cloaking effect can be achieved by active cancelation of the background magnetic field using the magnetic dipole.Compared with previous multi-unit designs, the single-unit design drastically reduces the number of control units Mud Masks required.It has potential applications in realizing the homogeneous field in wireless power transfer, magnetic resonance imaging, and other diffusion-based applications.
